The Ghost in the Boudoir

Laurel Farmer, Jennifer's best friend and the bridesmaid at her wedding, has an odd request. 

Could Jennifer's mother, Sally O'Brian come to her fiancée's house and see it if is haunted?  Sally knows that her daughter is dubious about Sally's ability to communicate with the dead. 

She also suspects that when she discovers the house is indeed haunted by the ghost of Laurel's boyfriend's previous girlfriend, Jennifer will not be happy with her.
